Best Buy's initial iPhone trade-in program proved a smashing success, and now the retailer is going back for seconds, giving consumers the chance to once more swap an iPhone 4 or 4S for a "free" iPhone 5 starting on Friday.

A set of high resolution images were posted to the Web late Tuesday claiming to show a side-by-side comparison of the display assemblies for Apple's iPhone 5 and a rumored next-generation model dubbed "iPhone 5S."

America's second-largest wireless carrier AT&T on Friday announced it will be pushing out an update to subscribers who own an iPhone 5 or 4S, with the new software supporting an FCC-mandated Wireless Emergency Alert system.

While Samsung's latest flagship smartphone, the Galaxy S4, unsurprisingly took the top spot at three of the four major U.S. carriers' stores in the month of May, Apple's eight-month-old iPhone 5 still remained the most popular smartphone at AT&T retail.

In another 16 markets, users of Apple's iPhone 5 and LTE-enabled iPads will now find that their devices are able to access much greater speeds, as AT&T has taken its 4G LTE coverage live in more areas across the U.S.

Starting this Sunday, electronics retailer Best Buy will be offering $50 off the purchase of any new iPhone model with a service contract, marking a rare discount opportunity for Apple's smartphone lineup.

Apple's iPhone 5 is getting another battery-boosting accessory from mophie, as the company announced the availability of the juice pack plus, which boosts the battery life of Apple's newest handset by 120 percent.

America's number two wireless telecom and Apple partner carrier AT&T recently started sending out promotional emails to certain iPhone 4S owners on its network, saying that they can take advantage of special trade-in pricing that effectively negates the upfront cost of a 16-gigabyte iPhone 5.

As its promotion of the iPhone 5 comes to an end, U.S. wireless provider T-Mobile has raised the price of Apple's flagship handset to $149; and a pair of hackers claim to have found a way to increase the handset's data transmission speeds by using the carrier's latest over-the-air update.

In a recently released commercial, Samsung once agains sets its sights on Apple's flagship iPhone, pointing out the "inadequecies" of the iOS device while at the same time touting new Galaxy features like Air View.
